TRACTION-ENGINE BEARING.

SPECIFICATION forming part of Letters Patent No. 294,793, dated March11, 1884.

' Application filed December 9,1582. (No model.)

- .To all whom it may concern.-

Be it known that I, FRANK F. LANDIS, a citizen of the United States ofAmerica, residing at Vaynesborough, in the county of Franklin and Stateof Pennsylvania, have invented certain new and useful Improvements inTraction-Engine Bearings, of which the following is a specification.

My invention relates to certain improvements in bearings fortraction-engines; and it has for its object the provision of strong,simple, and semi-spherical bearings, which will permit of theoscillation of a shaft journaled therein, and be provided with suitablefacili-' ties for lubricating said journals; and, with these main andother subsidiary objects in view, my invention consists in certainfeatures of construction and combination hereinafter described, andspecifically set forth in the claims.

Referring to the drawings, Figure 1 is a side elevation of so much of atraction-engine emtion of one of the bearings that rest upon the axleand support the boiler. Figs. 5 and 6 are details in elevation and plan,respectively, of one of the axle-bearings stated immediately above. a

Like letters refer to like parts in all the figures.

A represents a portion of the boiler; B, one of the frame-sills, formedof two parallel bars kept a short distance apart by thimbles and boltedtogether to support the boiler; and O, the housing or side frame for theactuatingshafts and gearing. D represents the axle of the traction orground wheels, all of which parts are fully described in otherapplications pending herewith, and therefore not described in detailherein, as they are not essential to an embodiment of my presentinvention.

The weight of the portion of the boiler shown and of its adjacentmechanism is borne by the axle D in suspension bearing-blocks d d ateach side of the frame-work, resting on the axle. Passing through anddepending from each block are two suspension-rods, (P, which extendthrough and below the sill B, and also pass through a cap, (1?,coil-springs (1*, and a base-plate, (P, and at their lower ends areprovided with heads (1 and at their upper ends with nuts al which aretightened sufficiently to slightly compress the spring between the capand base-plate.

By referring to Figs. 4, 5, and 6 it will be seen that each bearingcomprises two partsan inner bearing, (Z, and an outer bearing, dwhichconstitute a ball-and-socket bearing, on account of the form giventhereto. The inner bearing, (2, is on its lower face fitted to thejournal of the axle D, while its upper face is convex longitudinally andcircumferentially or spherically, to adapt it to fit a correspondingconcave recess in the lower face of the outer bearing, (1. Oil-ducts areprovided in each, and they are enlarged at the outer 'surface of eachbearing to hold a small supply, and a plate, 6, is secured by the bolts(1 over the upper bearing, and is perforated above its oil-ducts. Thewearing-surfaces of these bear ings may be provided with entire orpartial linings of Babbitt or other suitable metal, the usual means ofsecuring the same therein being employed.

By the construction thus far described it is apparent that the innersurface of the bearing (1 is adapted to the rotation of the axle D, andits outer surface, in connection with the inner surface of the bearing(1, is adapted to the oscillation of said shaft in a vertical plane bothabove and below its normally-horizontal position. Furthermore, the innerbearing, (1, is extended to form a square shoulder, which bears againstthe usual shoulder provided ono the axle, and, being suitably supportedin the housing or frame 0, no appreciable movement longitudinal of thebearings upon the axle occurs.

Referring back to Figs. 1, 2, and 3, E rep- 5 resents a bridge-piecesecured to the frame 0 by bolts F. This bridge is slotted centrally forthe passage and the vertical oscillation therein of the axle D, and isextended outwardly from the frame 0 to form a circular I00 journal, E,for the main gear -wheel, (not shown,) the latter being retained thereonby an annular flange, E (See Fig. 2.)

Vithin the journal E are formed oil-pockets G G, with supply-ducts 1/ 1at the top and de-' liVering-ducts r 1 at the bottom. The annular flangeor cap E is secured to the end of the journal E by bolts F in such aposition as to close the ends of the oilpocl ets. The cap E is slottedin like manner as the bridgepiece and thejournal E. Upon this journalthe usual traction-gear revolves, so that (in connection with connectingmechanism) power is conveyed from the motor to the tractionwheels.

This mechanism, being well known in the art and readily applicable byany mechanic conversant with this class of machinery, is not shown orfurther described herein.

The pockets G G may be filled with wool, cotton-waste, or sponge orother absorbent material, and thus a supply of oil may be retainedwithin and gradually be fed from them to the frictional surfaces of theflange and the traction-gear rotating thereon.

Having described my invention and its operation, what I claim, anddesire to secure by Letters Patent, is

1. I11 a traction -engine, an axle-bearing block provided with an innerand an outer bearing-surface, the former adapted to the rotation of theaxle, and the latter adapted to its Vertical oscillation, in combinationwith the sill B, formed of two parallel bars, suspensionrods betweensaid bars, and springs under said sills, substantially as and for thepurpose described.

2. The combination of the axle 1), blocks (1 and d, suspension-rods d,sills I3, caps d d", and springs between said caps, substantially as andfor the purpose described.

3. I11 a traction-engine, the combination of the frame 0 and axle I)with bridge E, having the journal Eand oil-pockets therein,substantially as and for the purpose described.

4. The combination, with the side frame, of the bridge-piece E, securedthereto, and having the journal E, with pockets G G,provided with theducts 91/, and the removable flange E, substantially as and for thepurpose described.

5. I11 a traction-engine, the combination of the axle 1), caps d d,springs 11, rods (1' and bearings d d with the slotted bridge E, havingthe annular journal E, substantially as and for the purpose described.

In testimony whereof I ailix my signature, in presence of two witnesses,this 4th day 01' December. 1882.
